F O Engineering has a strong background in designing and developing products and systems for the Aerospace industry. Products range from simple analog electromechanical actuator controls to high performance, redundant digital based system controls. All products are designed to withstand the harsh environments typical of Aerospace ground and flight applications, such as temperature, vibration, power conditions, EMI/EMC, etc.


F O Engineering’s extensive experience in system design and control electronics allows a one-stop-shop for electromechanical systems from concept through design, integration and production. Whether it’s a self-contained miniature motor controller or a large and complex system design, F O Engineering can help solve your problems.


Defense product design is driven by high performance in small packages. F O Engineering’s successful defense products incorporate high performance digital designs that occupy very small volumes, and are usually incorporated into the actuator itself, further reducing actuation system volume and enhancing overall system performance. Integration of the control electronics into the actuator housing allows F O Engineering’s system knowledge and expertise to ensure the success of the product, quickly identifying and correcting system issues as they arise.



5-GAT  5th Generation Aerial Target

F O Engineering (FOE), Inc. was selected by the 5GAT prime contractor, Sierra Technical Services (STS), Inc. to provide complete subsystem design solutions for the 5th Generation Aerial Target (5GAT) Drone air vehicle. 5GAT is a “Threat Representative,” “Low Observable” full-scale aircraft adversary, US Warfighters may encounter in an aerial combat situation. As a high-performance, unmanned, fighter-sized aircraft, 5GAT will be used for Air-To-Air and Ground-To-Air weapons evaluation, pilot training, and ground forces training. The FOE-responsible subsystems applications are as follows for the 5GAT air vehicle:

• Flight Control Actuation
• Hydraulics
• Fuel
• Electrical Power
• Landing Gear

• Steering

• Braking and Antiskid

• Tail Hook and Arresting Gear

• Secondary Utility Actuation (i.e. Propulsion Cooling Bay Vent Doors)

• Aircraft Cabling and Harnessing
